Hyaluronic acid gel for quick hydration and calmer, brighter-looking skin; pricey.

What the community says

Backed by 3 studies

A light gel serum with sodium hyaluronate and calcium pantothenate that layers under moisturizer. People reach for it when skin feels dehydrated, stingy, or post-retinoid; the catch is the eye-watering price and modest standalone payoff.
